As winter settles in across Southern Oregon, many homeowners are dealing with an influx of ants and other small pests seeking shelter indoors. While ants are typically more active in the warmer months, seasonal changes can drive them inside in search of food, water, and warmth. This year is no exception, as residents across the region report an increase in ant activity within their homes.
During the colder months, ants that normally reside outdoors begin searching for shelter in warmer environments. Southern Oregon’s climate, with its mild and wet winters, provides ideal conditions for ants to survive indoors. There are several key reasons why they might be making their way into homes. One of the main reasons is warmth. Ants are cold-blooded creatures, meaning their body temperature is regulated by their surroundings. When outdoor temperatures drop, they instinctively look for warmer places to establish temporary nests. Another major factor is the search for food. In the wild, ants rely on natural food sources that become scarce in winter, making crumbs, grease, sugary substances, and even pet food inside homes particularly attractive. Water availability is also crucial for their survival. Leaky pipes, condensation, and even houseplants provide reliable water sources during the drier winter months. Additionally, small cracks in walls, gaps around windows and doors, and openings in foundations allow ants to sneak indoors unnoticed.
Several species of ants are common in Southern Oregon, each exhibiting different behaviors. Odorous house ants, often called “sugar ants,” are tiny brown or black ants that emit a rotten coconut-like smell when crushed. Argentine ants, known for forming massive colonies, can be especially difficult to control. Pavement ants typically nest under sidewalks and foundations but will invade homes in search of food. Carpenter ants, larger than other species, are particularly destructive because they burrow into wood to build their nests.
Although ant infestations can be frustrating, there are several effective strategies to keep them at bay. One of the most important steps is eliminating food sources by storing food in airtight containers, cleaning up spills immediately, and avoiding leaving dirty dishes in the sink. Reducing moisture inside the home is also key, which can be done by fixing leaks, wiping down wet surfaces, and using a dehumidifier in damp areas like basements and bathrooms. Sealing entry points by caulking cracks in walls, around windows, and near doors is another essential step. Installing door sweeps can also help prevent ants from sneaking inside. Many homeowners find success using natural deterrents such as vinegar, lemon juice, and essential oils like peppermint and tea tree oil, which can disrupt ant trails and discourage them from entering. Setting bait traps is another effective method, as these attract ants to poison, which they then carry back to their colony, eliminating the source of the infestation. If the problem becomes unmanageable, hiring a pest control expert may be the best solution to prevent long-term issues.
Ants aren’t the only small invaders residents have to worry about during winter. Spiders, including common house spiders, often seek refuge in warm indoor spaces. Rodents such as mice and rats frequently enter homes in search of food and warmth, posing health risks. Silverfish, which thrive in moist environments, are often found in bathrooms, kitchens, and basements. Cockroaches, though less common in Southern Oregon, can still become a problem if they find reliable food and water sources inside homes.
Ants and other tiny pests can become a nuisance in Southern Oregon homes during the winter, but proactive measures can help keep them under control. By maintaining a clean home, eliminating access points, and using natural deterrents or bait traps, residents can minimize the chances of an infestation. If all else fails, professional pest control services are available to handle more severe issues. With winter well underway, now is the perfect time to take preventative steps and keep your home pest-free for the season ahead.
